PAPER-ROLL PROTECTOR.

Specification of Letters Patent.

Patented Jan. 8, iltlhld.

Application filed January 22, 1917. Serial No. 143,590.

To all whom it may concern:

Be itknown that 1, JOHN C. Breanne- HAM, a citizen of the United States,residing at Kansas City, in the county of Jackson and State of Missouri,have invented certain new and useful Improvements in Paper RollProtectors, of which the following is a specification. V

My invention relates to paper roll protectors, and my objectis toprovidesimple, inexpensive and efficient means of this character for protectingthe ends of paper from damage from the time it is formed into a rolluntil ready for use.

While my device can be used on any grade of paper to advantage it isintended more for use on rolls of print paper such as is used on rotaryprinting presses. The customary practice has been to cover the ends ofsuch rolls with many thicknesses of paper before shipment from the millto protect said ends from damage while the rolls are in transit andlying in the press rooms waiting to be used. Such paper covering is notonly comparatively expensive, but it fails to adequately protect theends of the rolls from becoming torn, indented, and otherwise damaged,thus annually resulting in considerable monetary loss.

By applying my devices to the ends of the rolls before shipment from themill, damage to the edges of said rolls is prevented, and as saiddevices can be used over and over again their initial cost is soon savedas only a few thicknesses of paper need be applied to the ends of therolls to protect them from becoming soiled.

In order that the invention may be fully understood, reference will nowbe made to drawings, in which:

Figure 1 is a side elevation of a paper roll with my invention appliedthereto.

Fig. 2 is a broken vertical section of one of the bands and a tighteningdevice therefor, constituting important features of the invention. j

Fig. 3 is a perspective view of a paper roll with the ends thereofprotected by two of the bands.

Fig. l is an enlarged, broken View of one of the bands with the endsthereof tied to, gather.

Fig. 5 is a central, vertical section on line VV of Fig. l.

Fig. 6 is a broken side elevation of a paper roll with one of the bandsand a plurality of retaining devices applied thereto.

Fig. 7 shows some of the parts disclosed by Fig. 5.

Fig. 8 is a broken detail plan View of a tightening device for drawingthe bands firmly around the paper roll preparatory to tying the ends ofsaid bands.

Referring 110w in detail to the various parts, A designates a paperroll, the ends of which are protected by a pair of bands 1, which areadapted to fit rolls of differentdiameters. Each band consists,preferably, of sheet metal of proper gage to give the requisitestrength. The overlapping end of the band 1 is, preferably, reinforcedat its upper side with aplate 2 secured thereon by suitable means, suchfor instance as bolts and nuts 3 and l, respectively. The edges of thenuts 4 adjacent the outer end of the plate 2, are beveled as indicatedat 5 for a purpose which will hereinafter ap pear. The overlapping endof the band 1, also, has an opening 6 and a slot 7, which latterregisters with a corresponding slot 8 in the plate 2. The underlappingend of the band 1 has a series of slots 10 corresponding to the slots 7and 8 for the pur pose of receiving a folded end of a flexible, metallictie 11, the opposite end of which is adapted to pass upward through theopening 6 and fold over a transverse pin 13, adapted to be seatedagainst the bevel sides 5 of the nuts 4, to prevent it from being pulledover said nuts by the tension exerted thereon by the tie 11.

15 designates a retaining device, two or more of which are placedbetween the roll A and the band 1 before the latter is drawn taut aroundsaid roll. Each retaining device 15 is of L form as disclosed by Fig. 6,so that one of its arms may lie against the adjacent end of the rollwhile its opposite arm is held firmly between the periphery of the rolland the underside of the band 1. The last-mentioned arm has an outturnedmarginal lip 16, which engages the inner edge of the band 1 and thusprevents said band from slipping longitudinally upon the roll A andexposing the edge thereof to possible damage- 18 designates a tighteningdevice for drawing each band 1 firmly about the periphery of the paperroll preparatory to securing. it with. a tie 11. Said tightening device18 may be changed more or less in construction, but I have found inpractice that the one disclosed in the drawings gives satisfactoryservice; Said device embodies a U-shaped member 19 adjustably secured toa U-shaped member 20, by a bolt-and-slot connection 21. Adjustment ofthe U-sha id member 19 is effected by a screw :23 extending throughalined openings in the trans verse forward ends of the members 19 and20, as disclosed by Fig. 8. Said screw 23 is provided with a head 21which bears against the member 19. aid screw 23 is also provided with anut 25 bearing against the rear side of the transverse forward end ofthe member 20. 'By rotating the nut 25 in one direction the U-shapedmember 19 may be slid forwardly upon the member 20 and by turning saidnut in a re verse direction the member 19 is drawn backwardly upon saidmember 20 for the purpose of adjusting a tooth 27 relative to aplurality of coacting teeth hereinafter described.

The tooth 27 is held firmly against the transverse portion of the member19 by the screw23 and a lock nut 28 threaded upon said screw, whichlatter is relieved of lateral stresses by flanges 30 on the rear portionof the member 19, which lap the edges of the member 1 0 and thusovercome any tendency of the member 19 rocking on the bolt 21 andbending said screw 23.

The rear ends of the member 20 are connected by a pivot 30 to a handlever 31, preferably, reinforced by a pair of oppositelydisposed straps32 connected at their forward ends by a pivot 33 to a dog 34, providedat its underside with a plurality of teeth 35 adapted to enter the slots10 in the band 1. As disclosed by Fig. 2, the teeth 35 slope slightly inone direction to engage the corresponding edges of the slots 10 and thusprevent said teeth from slipping out of said slots during the operationof tightening the band 1. For a like reason the tooth 27 slopes in areverse direction to the teeth 35 to en gage the corresponding side ofthe registering slots 7 and 8 in the band 1 and the plate 2,respectively.

In practice a band 1 is placed around one end of the roll by hand andbefore tightening said band with the device 18, the retaining devices 15are slipped into position between the'underside of said band and theperiphery of the roll. One end of the tie 11 is then folded and hookedover an edge of one of the slots 10 and its opposite end is passedupwardly through the opening 6. The band is then tightened about thepaper roll as firmly as possible by hand, after which it is firmlytightened with the device 18. the forward tooth 27 of which is insertedin the registering slots 7 and 8, whilelthe teeth 35 are placed incertain of the slots 10. The lever 31 is then grasped and swungbackwardly from the full line position to the dotted line positiondisclosed by Fig. 2. This forces the tooth 27 and the dog 34 toward eachother until the band 1 is firmly drawn about the paper roll. The weightof the lever 31 is such that after being swung back to the dottedposition it will hold the band 1 under tension and thus leave both handsfree to manipulate the tie 11, which is drawn taut by grasping the endprotruding through the opening 6 with a pair of pliers and pullingthereon 'until'all slack has bee'n taken up. Said end is'then foldedover the pin 13, which is' plaeed in position against the bevel 'ends 5of the nuts'4, where it is firmly held by thetension ofthe band 1. Theforegoing operation is repeated in applying the other band to theoppositeend of the roll. After the bands 1 have been applied to the rollthe tightening device 18 is removed, so that it will not interfere withhandling the roll preparatory to shipping the same.

After the roll has reached its destination the bands 1 are removed fromthe roll preparatory to using the same, and reshipped to the millforfurther use.

From the foregoing descriptiom'it is apparentthat I have produced paperroll protecting means embodying all the advantages above-enumerated, andwhile I have shown and described the preferred form of my: invention, Ireserve the right to make such changes in the construction, proportion,and arrangement of parts as properly fallwithin the splrit and scopeofzthe claims. i

Having thusdescribed my invention, what I claim and desire to secure byLetters Patcut, is: V

1. In a device of the character described, a band having slotted endsand adapted to be placed.circumferentially around paper rolls ofdifferent diameters, a flexible tie adapted to be hooked in one slot andpass through another slot to firmly but removably secure said endstogether to permit removal of the band from the roll, members on one endof the band provided with beveled sides, and a pin adapted to be securedto one end'of the tie and abut said beveled sides.

2. In an edge protector for paper rolls, a band having overlappingslotted ends, a tie having one end hooked through one slot of the underband end and extending through one of the slots of the upper band end,and means to adjustably secure the last named tie end'to the upper bandend at a point above the latter. i

3. In an edge protector for paper rolls, a band having overlappingslotted ends,a tie having one end hooked through one slotof the underband end and extending through one of the slots ofthe upper band end,and a member borne by'and located above said upper band end, said memberbeing arranged to allow the other end of the tie to be wrapped partlyaround said member.

4. In an edge protector for paper rolls, a band having overlappingslotted ends, a tie having one end hooked through one slot of the underband end and extending through one of the slots of the upper band end,and a pin extending transversely of the band, and means to anchor thepin whereby the last named tie end may be Wrapped around the pin so asto frictionally hold the latter against the anchoring means.

5. In an edge protector for paper rolls, a band having overlappingslotted ends, a tie having one end hooked through one slot of the underband end and extending through one of the slots of the upper band end,means movable to engage the last named tie end, and means against whichsaid means abuts to hold the same in place by the tension of the tie.

6. In an edge protector for paper rolls, a band having overlapping ends,a flexible tie connected to the under end and extending between the endsand then above the upper end, and means to engage and adj ustably securethe tie to said upper end.

7. In an edge protector for paper rolls, a band having overlapping ends,a flexible tie connected to the under end and extending between the endsand then above the upper end, a pin formed to allow the outer end of thetie to be wrapped therearound, and abutment means on the upper band endto hold the pin against movement exerted by the tension of the tie.

8. In an edge protector for rolls, a band having overlapping ends, aflexible tie connected to the under band end and extending above theupper band end, means independent of the tie for adjustably engaging theupper end of the tie, and means to secure said last named means in placeto allow same to be removed upon mere release of the tie tension.

9. In an edge protector for rolls, a band having overlapping ends theupper of which is slotted, a flexible tie, means to secure one end ofthe tie to the under band end, said tie having its opposite end passedthrough the slot of the upper band end and extending toward the freeextremity of the latter whereby upon drawing said tie taut same Willmove the band ends in opposite directions, and means to secure oppositeend of the tie against movement after adjustment thereof.

In testimony whereof I atfix my signature, in the presence of twowitnesses.
